Armies of the Tribes of Israel converged upon the tribe of Benjamin in the aftermath of the "Concubine at Givah" incident, in a war which nearly brought about the extinction of the Benjaminites (as related in the Book of Judges, chapters 19-2). The event occurred during the judgeship of Othniel ben Knaz, who led the people of Israel in the years 2533-2573 from creation (1228-1188 BCE).
On Simchat Torah we dance with our feet, not with our heads.
We are celebrating the Torah, and the Torah is something we study with our heads. But we dance with our feet, not with our heads.
If we would dance with our heads, each one would dance a different dance, each in a different space, some with friends but not with others, some as lonesome souls.
One head is higher, one is lower, one is here on earth, the other in the clouds or beyond, and some minds know only their own space that no one else can know.
But we dance with our feet, and all our feet are here on the same earth—none higher and none lower. So now we can all dance as one, with one heart, as a single being.
Now there is no loneliness, only joy.
